摘要

Correct modelling of turbogenerators is difficult, as currents are flowing during transients not only in the field and damper winding but also in the solid rotor iron. To model this effect especially at high frequencies new model structures, so called ladder-networks, r introduced. Their parameters are dien- tified by combining the standstill frequency response mea- surements with the results of the standardized three phase no-load short-circuit test. By means of combination the er- rors in the standstill frequency responses, caused by the iron nonlinearity and the contact uncertainty of the slot wedges at standstill, are expected to be reduced.
